There are 28 students in a class. The ratio of girls to all the students is \( 3: 7 \). How many boys are in the class? Go to the Lesson

To find the number of girls and boys in the class based on the ratio, start by using the given ratio of girls to total students, which is \(3:7\). Since there are 28 students total, you can calculate the number of girls by finding the fraction of the total students represented by the ratio of girls, which is \(\frac{3}{7}\). Therefore, the number of girls is \(\frac{3}{7} \cdot 28 = 12\). Now, subtract the number of girls from the total number of students to find the number of boys: \(28 - 12 = 16\). So, there are 16 boys in the class.
